Description

导尿管
技术领域：
本发明涉及医疗器械领域，具体是涉及一种导尿管。
背景技术：
导尿是临床上常见的医疗操作之一，适用于因下尿路梗阻或神经源膀胱等引起的尿潴留，导尿操还应用在抢救危重病人、为手术期准备、膀胱内药物灌注或膀胱冲洗等情况。
目前临床上应用的导尿管有双腔结构和三腔结构的，其中双腔的导尿管包括导尿通道和注水通道，导尿管前部设有与注水通道相连通的球囊，位于球囊前方的导尿管上设有尿液进口，导尿管前端固定有子弹头形的端头；三腔的导尿管还包括冲洗通道，球囊前端的导尿管上设有与冲洗通道相连通的开口。但是这些现有的导尿管球囊前方的导尿管和子弹头形端头的总长度有2—3㎝，患者使用时端头与膀胱内壁粘膜接触，短时间内造成患者不同程度的膀胱内壁粘膜炎性改变、增生、破溃、出血等，长时间留植会导致粘膜广泛炎性改变，部分患者存在较严重的膀胱刺激现象，甚至会导致膀胱痉挛。
而肾盂球囊型造瘘管由于无端头，临床上对于膀胱造瘘患者、膀胱刺激症状严重者可予留植以减轻症状，但由于造瘘管前端无端头，无法沿尿道植入。
发明内容：
本发明所要解决的技术问题是提供一种可将尿管对膀胱粘膜的副损伤降至最低并可沿尿道植入的导尿管。
上述目的是这样实现的：它包括管体，管体内设有注水通道，注水通道后端设有第一阀门，管体前部设有球囊，所述球囊与注水通道前端相连通；其特征是：在球囊前部设子弹头形的高压水囊，高压水囊后部设有插头，所述的插头插在管体前端内，即插头外壁与管体前端内壁接触，管体内设与高压水囊相连通的高压水注水管，高压水注水管的前端与高压水囊固定在一起，所述高压水注水通道的后端设有第二阀门。管体前端为尿液进口，管体后端与尿袋连接。
还可在管体内设冲洗通道，所述冲洗通道前端的开口位于球囊的前方。
本发明的优点是：植入时经高压水注水管向高压水囊内注入高压水，使高压水囊膨胀成子弹头形，增加尿管延尿道或造瘘口植入的顺应性，待管体经尿道进入到膀胱内后，由注水通道向球囊内注水，使球囊膨胀对导尿管定位，排出高压水囊内的水，向外拉高压水注水管，将高压水囊拉出导尿管外，尿液从导尿管的前端开口进入到管体内，再进入到尿袋中。由于植入后将高压水囊取出，所以会将现有尿管对膀胱内壁粘膜产生的副损伤降至最低，另外由于在植入时向高压水囊内注水，该尿管具备现有尿管良好的植入顺应性，所以解决了肾盂球囊型造瘘管难以植入的问题。
附图说明：
图1是本发明的结构示意图；
图2是图1的A-A视图。
具体实施方式：
参照图1、2，它包括管体1，管体内设有注水通道2，注水通道后端设有第一阀门3，管体前部设有球囊4，所述球囊与注水通道前端相连通；其特征是：在球囊前部设子弹头形的高压水囊5，高压水囊后部设有插头6，所述的插头插在管体前端内，即插头外壁与管体前端内壁接触，管体内设与高压水囊相连通的高压水注水管7，高压水注水管的前端与高压水囊固定在一起，所述高压水注水通道的后端设有第二阀门8。管体前端为尿液进口，管体后端与尿袋连接。
还可在管体内设冲洗通道9，所述冲洗通道前端的开口位于球囊的前方。
